In this paper, using an efficient change of variables we refine the Hyers-Ulam stability of the alternative Jensen functional equations of J. M. Rassias and M. J. Rassias and obtain much better bounds and remove some unnecessary conditions imposed in the previous result. Also, viewing the fundamentals of what our method works, we establish an abstract version of the result and consider the functional equations defined in restricted domains of a group and prove their stabilities.

In this note, by using the fixed point alternative, we investigate the modified Hyers-Ulam-Rassias stability for the following mixed type functional inequality which is either cubic or quadratic: $\parallel$8ｆ(x-3y) + 24f(x+y) + f(8y) -8〔f(x+3y) + 3f(x-y) + 2f(2y)〕$\parallel$$\leq$$\varphi$(x,y).

In this work, we obtain intersection theorem, analytic alternative and von Neumann type minimax theorem in G-convex spaces. We also generalize Ky Fan minimax inequality to acyclic versions in G-convex spaces. The result is applied to formulate acyclic versions of other minimax results, a theorem of systems of inequalities and analytic alternative.

This study attempted to explore parents'perceptions on character and character education for their children using a focus group interview method. According to previous research, the concept of character consists of wholeness of three components: relationship, individuality, and morality. This study investigated how parents' perception differ from the widely agreed concept of character. Forty-four mothers and ten fathers participated in eleven focus group interviews. The results showed that parents recognized social relationship and self realization as two most important components of character education of children. However, the parents paid less attention on morality and wholeness. The parents conceptualized character as an alternative to academic achievement. For example, they considered self realization as an alternative to academic achievement. These tendencies could be a barrier in character education in family. Based on these findings, this study recommends that parent education should take more attention on character education in family and help parents develop a balanced understanding on the concept of character.

As for the practical purpose of mathematics education, the extrinsic purpose is emphasized. As an alternative to this, a discussion on mathematics education as a character education is urgently requested. It can be said that the main purpose of learning mathematics is to have a form of life that values the form and structure of mathematics. The epistemological basis of such an idea can be seen as based on Kant's philosophy. Kant's epistemology can provide one answer to the question of the intrinsic purpose of mathematics education.

Today, design is considered to have competitive power for a county, so there has been various efforts such as education, publicity and development, etc. Design has long been a national material, and Korea Institute of Design Promotion(KIDP) was inaugurated for the purpose of education, publicity, development and the management, public ownership, support of the contents. Laying stress on the results, however, the design education for children which would be the heart of a world design power is short of both investment and systematic study of education. Now that the design education for children is being active, the cultural spaces are needed to transform the current system focused on schooling and textbooks into the participating, experiential ones by the interesting, educational, and entertaining presentation. The children design exploratorium should make children have their own feelings, and present communicative methods considering children's cognition and behaviors. So, in this study, I'd like to analyze characteristics of the participating and experiential exhibition, and present a children design exploratorium as an alternative plan by the application of adequate methods to the exhibition medium, and the analysis of current exploratoriums' features case by case. The children design exploratorium is the place to maximize the educational effect of design by children's easier and exciting participation, which would offer an unique exhibition place for children to comprehend designs. In this study, on the basis of the alternative presentation of children design exploratoriums, I would refer to the future direction of the 21st century pavilions, the search for the exhibition items for active design education, and the contribution to practical plans.

The purpose of this study is to find out how career education has been positioned in secondary school home economics education, and to clarify the identity of career education as one part of home economics education. Furthermore, this study tries to give alternative teaching-learning strategies for life career education across the life span. It deals with home economics curricular and journals. It also analyses the 21 sorts of home economics textbooks and one career and vocation textbook in secondary school, which are supposed to be based on the newly revised 2007 curriculum. As a research method this study takes a qualitative approach. As follows are the results of this study. First, career education has been positioned as one part of home economics education. Second, both career and vocation education and home economics education have dealt with the contents related to career such as self-understanding, career-exploring, deciding-making related to career, career-designing. However, career and vocation education has focused on 'vacational career', whereas home economics education has focused on 'life career' across the life span. Third, this study proposed three alternative teaching-learning strategies for life career education across the life span.

This study examined the influences of cognitive conflict and anxiety induced by a discrepant event and an alternative hypothesis, attention, and effort on conceptual change. Two hundred three students having misconceptions about density were selected from 462 seventh graders based on the results of a preconception test. Tests of cognitive responses and anxiety to a discrepant event were administered before and after presenting an alternative hypothesis. Computer-assisted instruction (CAI) was then provided to students as a conceptual change intervention. Tests assessing attention and effort allocated to the CAI, and conceptual understanding were administered as posttests. Cognitive conflict induced by a discrepant event was found to increase after presenting an alternative hypothesis. Pre-cognitive conflict induced by only a discrepant event exerted a direct effect on post-cognitive conflict induced by a discrepant event and an alternative hypothesis. Post-cognitive conflict had a direct effect on conceptual change. Pre-anxiety decreased after presenting an alternative hypothesis. Pre-anxiety influenced post-anxiety, and this influenced on conceptual change via effort negatively. Attention had a direct effect as well as an indirect effect on conceptual change via effort. These results suggest that the strategy presenting both a discrepant event and an alternative hypothesis to students in concept learning could facilitate conceptual change by inducing more cognitive conflict or active participation of students through the decrease of anxiety than that presenting a discrepant event only.

Purpose: This study was done to examine the experience of school health instructors in applying complimentary and alternative medicine (CAM). Method: The participants were 215 health instructors working in elementary schools in Busan. Data were collected from Dec. 1, 2004 to Mar. 10, 2005 and were analyzed using SPSS WIN 10.0. Results: Most of the health instructors had knowledge about CAM. Among the various CAM methods, acupuncture was the most widely known at 78.6%. While 53.5% had no experience in CAM education, 46.5% had been trained. Slightly over half (52.1%) had used CAM at school and based their decision on personal experience. As to applicability of CAM at school, 72.1% thought CAM was applicable, and 78.7% of this group considered alleviation of symptoms and assistance in the treatment process as the reasons for their answer. There were significant differences in responses as to the applicability of CAM according to age (p=.002), work experience (p=.004) and educational background (p=.002). Conclusions: The above results suggest that there is a need to develop a professional education program on complimentary and alternative medicine to assist school health instructorsto plan nursing interventions using CAM which are individualized and practical.
